施氮与刈割对青引1号燕麦产量的影响

Effect of applying nitrogen and cutting on yield of Qingyin No.1 oat

以青引1号燕麦为研究对象,研究了不同施氮水平和处理方式对其鲜草、秸秆和种子产量的影响。试验得出:处理F的鲜草总产量达62 758.8 kg/hm2,处理C的秸秆产量达8 434.6kg/hm2,处理A的种子产量达4 807.1 kg/hm2;在不同施氮水平下,刈割处理可提高燕麦鲜草产量;不刈割处理其秸秆、种子产量较高,且有利于收获种子。

Oat variety Qingyin No.1 was used as the research object to study effect of different application levels and different treatment method on yield of fresh grass,straw and seed of oats.The experimental results showed that the total fresh grass yield reaches 62 758.8 kg/hm2under F treatment.Straw yield reaches 8 434.6 kg/hm2 under C treatment.Seeds yield reaches 4 807.1 kg/hm2 under A treatment,indicating that different amount of nitrogen application and cutting treatment can increase fresh grass yield of oat.Straw yield and seed yield of oats are higher and benefit harvesting seeds under non-cutting treatment.
